What is common bile duct (CBD) exploration?
The
CBD is a tube connecting the liver, gallbladder, and
pancreas to the small intestine that helps deliver fluid to aid in digestion.
The CBD exploration is a procedure used to see if a stone or some obstruction
is blocking the flow of bile from your liver and gallbladder to your intestine.
When is it used?
If a stone or
obstruction is blocking the CBD, bile can back up into the liver causing
jaundice. Jaundice is when the skin and white of the eyes become yellow.
The CBD might become infected and require emergency surgery if the stone or
blockage is not removed. This procedure can be done during the removal of the
gall bladder.
An alternative would be an ERCP (Endoscopic retrograde cholangiopancreatogram)
or not having treatment. You should discuss these options with your doctor.
Preparation for CBD exploration
- Eat light the day before
- Have nothing to eat or drink after midnight
- Take only medicines as instructed the morning of surgery
During the procedure
- General anesthesia relaxes your muscles and puts you into a deep sleep, so
you will feel no pain.
- The doctor will make a small incision in the abdomen, locate the CBD, and
inject a dye into the duct. Your doctor will then take an X-ray, which will
show where the stone or obstruction is located.
- If stones are found, the doctor will make a cut into the duct and remove
them.
- A tube might be inserted into the duct and out the skin to drain bile into a
bag.
- The bag will remain in place anywhere from seven days to many weeks.
- The doctor might repeat the dye procedure before removing your tube.
Post operation instructions
You will
be required to stay in the hospital for one to four days. You will also be asked
to avoid strenuous activity for four to six days, and will require a follow-up visit
with your doctor.
Benefits of CBD exploration
The
surgery should alleviate your discomfort and will decrease the chance of
infection and jaundice.
Risks
As with any surgery there are
risks, although minimal:
- Complications of general anesthesia
- Swelling or scarring of the duct
- Bile leak
- Bleeding
- Infection
Call the doctor if:
Immediately call
your doctor if you have any of the following symptoms:
- Increased abdominal pain
